Otto Hiichstitdter, Munich, Germany Application October 18, 1934, Serial No. 748,935 In Germany October 20, 1933 3 Claims. (Cl. 215-39) This invention relates to a closure for conthe tongue and the cover there is an opening 5" tainers of all kinds, more particularly bottles, which facilitates gripping the tongue. glasses and the like, which is held on the con- When.the closure cap and securing cap are aptainer by means of an external ridge on the open plied to the container, for example a bottle neck,

constructions, as for example, crown corks and one within the other. For this purpose the seclaw stoppers for bottles. These however, do not curing cap has holding members 8 and 9 provided fulfill all the requirements that they should be on the marginal part 2. As shown in Fig. 3 the not only cheap in manufacture and simply and holding members 8 are made short and embrace 0 securely attached to the container, but also the edge or the claws ill of the closure cap. On 10 readily removed therefrom without it being possithe other hand the holding members 9 are made ble to open the closure unintentionally. so long that they enclose claws I0 so that these These requirements can be met according to long holding members are drawn in and held fast the invention by the closure being formed from when the closure is placed on the container. The

According unintentional loosening, for example, in transto the invention, above the actual closure cap a port. The arrangement of the longer holding securing cap is arranged, the marginal part of members is preferably such that the one holding which is folded in the manner of a crown cork, member 9 is attached to the perforated marginal pressed against the holding parts of the closure part 6 and the other holding member is at the 20 cap and provided with a tongue. opposite edge of the cap.

When the new container ginal part 2 of which according to the invention, is used for bottles the well-known devices for 40 is crimped. This securing cap is arranged over applying the stopper may be employed. It is also 40 the actual closure cap which contains a packing. important that the closure cap and securing cap This closure cap may have various shapes and when combined according to Figs. 1 to 5, should in Figs. 1 to 3 it is illustrated as a claw or expansibe pressed on the container simultaneously in ble cap 3, with packing plate 3a, and in Figs. 4 one operation.

The securing cap is of practically nal portion of the securing cap is pressed tightly the same shape for both the closure ca'ps illuson to the holding part of the closure cap as illustrated. According to the invention it has a trated in Fig. 6 by way 'of example, to a claw cap. tongue 5 for tearing oil, which is preferably This may, of course, also be constructed as a formed from the metal cover part of the cap as spreading cap. 50 shown in the drawing, the marginal part con- The closure is opened by the tongue 5 being nected with it being bounded by a double radial raised somewhat from the cover of the securing perforation I. cap, and then being gripped and torn downward At the beginning the tongue 5 is provided with strongly in the directi n In this Way the D 65 a flat edge 5' so that between the beginning of foration 7 is torn and the tongue, the marginal for example, in Fig. '7

2 part I and one holding member I are removed. The remaining part of the cap can easily be removed by bending back the endsin the direction of the arrows B and C. If the cap consists of hard or thick material the bending can be facilitated, if necessary, by a slot l2 in the cover part. After removing the securing cap the actual closure cap is removed. when a spreading cap is used this is effected by pressing on the metal part of the cover. With other closure forms of closure caps these may, according to the invention, consist of suitable thin or soft sheet material so that they can easily be removed.

If the holding member 8 of the marginal part 6 of the tongue is, according to the invention, made so long that it comes to lie between the cover part of the closure cap and the edge of the opening of the container the closure can be opened very easily. If the perforation is torn and the tongue is then pulled upwards the hold ing member 9 acts as a kind of lever which lifts off the closure.

If for the closure cap a crown cork of soft material is provided this has the advantage that the cap when required can be put back and closed on the container, for example the bottle, which is not possible with the known very hard crown corks.

The closure according to the invention has further the advantage that when using spreading cap closures it is no longer necessary for the cap or the bottle ridge to be accurately dimensioned in order to ensure satisfactory closure. While previously the smallest deviation in this respect caused troublein the proper seating of the cap, with the present device the deviation may be considerable without the tight sealing of the closure being affected. On account of this independence of accurate dimensions it is, for example, possible to place spreading cap closures on crown cork bottles.

The closure according to the invention can be applied to containers of various kinds. Thus, a closure for a rectangular sheet metal box is illustrated. In this case it is not necessary to provide over the closure cover ll 'a'similarly shaped crown cork cap. The metal part of the securing cap M can be suitably apertured, as shown at l5. For easy opening of the closure two tongues I6 are here provided.

The use of the above described closure has further the advantage that the closure can be provided with an advertising imprint or an indentation. This is not possible for example, with some known closures, for example cap closures, because the closure cap is too hard.

What I claim is:

1. A closure for containers, more particularly bottles, comprising an inner expansible cap adapted to be releasably secured to the mouth of a. bottle, an outer crimped cap disposed over said expansible cap and adapted to secure the latter over the bottle opening, means on the outer edge of the crimped cap for embracing the outer edge of the inner expansible cap for releasably retaining the expansible cap within the crimped cap when in an expanded condition, and means on said crimped cap for facilitating the removal of the outer cap.

2. A closure for containers, more particularly bottles, comprising a frequently usable expansible cap, a crimped cap arranged over the expansible cap and adapted to secure the latter, retaining tongues on the edge of the crimped cap for connecting the latterto the expansible cap, and a tear-off tongue indicated by perforations, said tear-off tongue lying in the plane of the crimped cap and beginning at a distance from the edge of an opening in the crimped cap, one of the retaining tongues on the edge of the crimped cap forming an extension of the tear-off tongue and. being continued under the edge of the expansible cap beyond the seal of the latter.

3. A closure for containers, more particularly bottles, comprising a frequently usable inner crimped cap of soft material, an outer crimped cap arranged over the inner crimped cap and. adapted to secure the latter, retaining tongues on the edge of the outer crimped cap for connecting the latter to the inner crimped cap, a tear-off tongue indicated by perforations, said tear-01f tongue lying in the plane of the outer crimped cap and beginning at a distance from the edge of an opening in said outer crimped cap, one of the retaining tongues on the edge of the outer crimped capforming an extension of the tear-off tongue and being continued under the edge of the inner cap beyond the seal of said inner cap.
